Partial discharge monitoring wireless sensor network communication method based on dynamic game

Abstract

The invention discloses a dynamic game-based partial discharge monitoring wireless sensor network communication method, which comprises the following steps of: S1, constructing a forwarding node alliance in a dynamic planning manner, searching neighbor nodes by taking a radius as a basis, and screening forwarding nodes by taking residual energy as a basis; S2, the delineated neighbor nodes play a game, and a forwarding queue is constructed according to the maximum membership degree principle; S3, the source node and the queue head node establish a communication link for message forwarding, and meanwhile, the second node and the third node serve as standby next-hop nodes; and S4, the nodes in the alliance not in the standby range are firstly released, and the standby nodes are released after the message is successfully forwarded. The residual energy parameter is introduced during multi-path message forwarding, so that the success rate of message forwarding is improved; the two parameters of the spatial distance and the residual energy are integrated to construct a forwarding queue, so that the message forwarding rate can be improved; and a method of orderly releasing the forwarding tasks after the forwarding tasks are completed by the dynamic game alliance is adopted, so that the node multiplexing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically relates to a communication method of a wireless sensor network for partial discharge monitoring based on a dynamic game. Background technique [0002] Partial discharge is an inevitable phenomenon in the operation of high-voltage power equipment such as transformers and switchgears, and is an important cause of insulation breakdown of high-voltage equipment. Therefore, it is necessary to strengthen the monitoring of the equipment in operation. When the partial discharge exceeds a certain level, the equipment should be taken out of operation and repaired or replaced. [0003] Traditional partial discharge detection uses handheld detection equipment to detect key parts during manual inspections. With the development of Internet of Things technology, the application of partial discharge on-line monitoring based on sensor technology is becoming more and m...
